**3.2 Data on processed biogases**

As a basis for further considerations, data for the biogas compositions as specified in Table 6 will be used. Further accompanying substances occurring in the biogas have not been taken into account, because they vary too greatly depending on the fermented substrates and type of processing.


Table 6. Examples of the composition of processed biogases

A processing level of 99.5% vol. methane is attainable and is state of the art. The N2 and O2 levels are 0.3 and 0.1 vol -% and remain constant for the calculations at these initial methane levels. The CO2 content conforms to the relevant selected methane content within the specified range.
